I'm off to a wedding in September and haven't got a clue what to wear, I'm not really a dressy kind of girl and I almost always live in black (but not adverse to a bit of color for the wedding) so I'm at a loss. I'm size 14, 5'10 and kind of like the retro/vintage style. I hate my arms so would need something to cover them and I don't want to pay a fortune as it'll probably not get worn that often. Any suggestions?
